Respected Teachers & Dear Students,
Welcome back to my YouTube channel Physics with Kiran Aslam...!

CHAPTER#2 KINEMATICS
CONCEPTUAL QUESTIONS

Differentiate between rest and motion. With the help of example, show that rest and motion are relative to observer?

What are different types of motion? Define each type of motion with examples from daily life.

What are scalars and vectors? Give examples. How are vectors represented symbolically and graphically?

Define the term position. Differentiate between distance and displacement.

Differentiate between speed and velocity. Also define average speed, uniform and variable speeds, average velocity, uniform and variable velocities.

What are freely falling bodies? What is gravitational acceleration? Write down sign conventions for gravitational acceleration? Write three equations of motion of a freely falling body?

Draw distance-time graphs for rest, uniform speed, increasing speed and decreasing speed.

Draw speed-time graphs for zero acceleration, uniform acceleration, and uniform deceleration. Also show that area under speed-time graph represents distance covered by the body.
